Hi,

Goto transaction <b>ABAPDOCU</b> --> ABAP Objects.

Lot of programs there based on OOPS concept.

Check the below links too:

Aday,

I would suggest that you take SAP's BC401 - ABAP Objects.

The differences are large. This class will introduce you to the ideas of OOP.

The goal of OOP is reusable code (objects). "Standard" ABAP is more procedural in nature - based on it's roots in COBOL, Pascal, etc.

Hello Aday,

Check the syntax and examples in the F1 help in the workbench.

Go to Transaction code SE80. Enter the syntax..Place the cursor on the class and press F1. It helps you all the features in ABAP with best syntax and examples..

Example

CLASS C_COUNTER DEFINITION.

PUBLIC SECTION.

METHODS: SET_COUNTER IMPORTING VALUE(SET_VALUE) TYPE I,

INCREMENT_COUNTER,

GET_COUNTER EXPORTING VALUE(GET_VALUE) TYPE I.

PRIVATE SECTION.

DATA COUNT TYPE I.

ENDCLASS.

CLASS C_COUNTER IMPLEMENTATION.

METHOD SET_COUNTER.

...

ENDMETHOD.

METHOD INCREMENT_COUNTER.

...

ENDMETHOD.

METHOD GET_COUNTER.

...

ENDMETHOD.

ENDCLASS.

Regards

Madhavi.
